If you want to consider the travesty of medical advice vs evidence during COVID-19, vitamin D is an amazing example
100s of millions of people have self-medicated/been treated with vit D for COVID. The evidence base is trash

A living Cochrane systematic review last updated May 2021 gives you an idea of this - as of 14 months into the global pandemic, there are 3 published RCTs on vitamin D

And look, it's never been tremendously likely that vitamin D was the key ingredient to banishing COVID-19, but it is wild that so many people have taken it for the disease and we still don't even know if there are harms to that or not
Also worth noting that, despite there being basically no good evidence about vitamin D/COVID-19, there are somehow nearly 1,000 PUBLISHED PAPERS on the topic which begs the question of what the point of academia is in the first place
Anyway, I'm still skeptical about vitamin D but the point here is that if someone asks you "can vitamin D help with COVID-19" the only correct answer is a GIANT SHRUG and that is a heinous situation at this point in the pandemic
